3) Statement that the establishment is subject to the provisions on High Risk Facilities (ZDR) and that the Provincial Headquarters of the State Fire Service (KW PSP) received the ZDR notification

The LNG terminal is a complex of interconnected process installations, equipment and structures used for:

  • receiving liquefied natural gas (LNG) from LNG ships (methane carriers),
  • LNG storage,
  • regasification of stored LNG and supply of natural gas to the gas transmission network,
  • loading LNG into tanker trucks.

The LNG Terminal, due to the amount of LNG and natural gas contained in the process storage tanks and process installations, is subject to the legal provisions applicable to high risk facilities (ZDR).

Notification of the LNG Terminal as ZDR to the Provincial Headquarters of the State Fire Service and Provincial Environmental Protection Inspectorate in Szczecin was submitted on 4.11.2013.

In accordance with the ZDR regulations, the following have been developed and implemented at the LNG Terminal:

  • Failure Prevention Program,
  • Safety Report, which proves that the LNG Terminal fulfils the applicable safety standards and the multi-layered technical safeguards systems in place as well as procedural and organisational safety management system measures ensure that they are capable of preventing and limiting the consequences of potential failures to an acceptable risk level.
  • Internal Operational and Rescue Plan describing rescue procedures to ensure readiness of the LNG Terminal to undertake rescue operations in case of emergency or failure.

These documents were, in accordance with the law, adopted and/or approved by the West Pomeranian Provincial Inspector of Environmental Protection and the West Pomeranian Provincial Chief of State Fire Service. 

4) Description of the measures applied and the procedures to be followed in the event of an industrial accident

Good engineering practices

  • are based on global standards used in the design, construction and operation of LNG Terminals.

Mechanical and structural integrity

  • the adopted quality assurance programs, including adherence to global design standards, material specifications as well as manufacturing and construction procedures, guarantee conformity of the LNG Terminal with global standards,
  • LNG tanks in full safety casing, outer concrete containment tank is capable to contain the stored LNG in case of failure of the internal steel tank,
  • monitoring of equipment operational parameters and conformity with design limit values, as well as protection systems against exceeding design limit values,
  • pressure build-up protection systems, used for the safe evacuation of LNG and gas streams in the event of an overpressure or fire.

Multi-stage protection system

  • if the first stage of protection in a specific point of the technological process fails, then the next stage is initiated to stop escalation of the failure risk,

Safety management system

  • ensures that the operation and management of the LNG Terminal complies with the regulations and best practices of global LNG terminals,
  • the safety management system at the LNG Terminal is covered by the Integrated Management System based on ISO 9001, 14001, 18001,
  • recording and analysis of potentially hazardous events and emergency situations,
  • routine assessment of process risk management to ensure the level of risk acceptable to people, the environment and property in the operation of the LNG Terminal.

Safe system of work

  • selection of personnel with appropriate safety competences,
  • a permit to work system, permits issued by authorised persons, to ensure that work is safe for people, property and the environment,
  • proper supervision of conformity with organisational and procedural regulations as well as occupational safety.

Security

  • LNG Terminal’s area surveillance systems against unauthorised intrusion,
  • monitoring the movement of people and materials at the gates and within the LNG Terminal site,
  • a specialist armed formation responsible for the physical protection of the LNG Terminal.

Fire protection strategy

  • direct protection - safe distances, fire resistant materials,
  • passive fire protection - protection with fireproof coating, water spraying, preventing collapse of structures or equipment supports exposed to prolonged fire,
  • integrated fire safety management system - used to detect hazards caused by gas leakage or low temperature (LNG), fire, fulfilling the functional and safety requirements through alarming, automatic activation of the system to cut off the endangered zone, shutting down the installation and activation of rescue and firefighting systems,
  • the emergency shutdown system logic is implemented by an ESD system which is independent of the primary process control system,
  • collecting emergency LNG spills into retention basins with a foaming system to reduce LNG  vaporization and safely disperse LNG vapours,
  • emergency electrical supply - diesel generators to provide reliable electrical power for safety systems.

Rescue operations:

Rescue operations to protect people, environment and property from the effects of an industrial accident are defined in the Internal Operational and Rescue Plan, with the use of:

  • two fire-fighting water systems - a fresh water fire-fighting network with a water tank, capacity of 1700m3, and a seawater fire-fighting network, each with duplicated pumps and standpipes,
  • controllable water and foam cannons for structure cooling or fire fighting,
  • water curtains to limit the spread of LNG and gas vapours,
  • water spraying systems for equipment exposed to fire,
  • foam generators to cover LNG spills,
  • fixed fire-fighting systems in buildings,
  • portable fire fighting equipment,
  • a system for alarming and broadcasting voice messages about the threat.

Initial rescue operations and evacuation of personnel in the event of an emergency are carried out by trained LNG Terminal personnel in accordance with the Internal Operational and Rescue Plan. If necessary, rescue and firefighting operations are taken over by the State Fire Service. 

5) Names, types and hazards posed by hazardous substances determining the ZDR classification   

Substances which, due to their quantity, determine classification of the LNG Terminal as a high risk facility:

Liquefied natural gas or LNG:

  • is a colourless, odourless, non-toxic liquid, lighter than water, with a temperature of approximately minus 160°C,
  • the composition of LNG is the same as that of natural gas,
  • LNG vapours at temperatures below minus about 100°C are heavier than air and remain near the surrounding surface,
  • LNG vapours are extremely flammable, forming a combustible mixture with air, similar to natural gas.

Natural gas:

  • is colourless, odourless, non-toxic, extremely flammable, lighter than air,
  • it consists primarily of methane with minor amounts of other hydrocarbons and nitrogen,
  • in the concentration range of 5 ÷ 15 %, natural gas forms a flammable mixture with air and burns with a hardly visible flame.

6) Description of the types of accident hazards, their potential effects on the population and the environment

The rules adopted for the design and construction as well as for the operation of the LNG Terminal limit the risk of an industrial accident to very low probability, the consequences of which may extend beyond the LNG Terminal premises to the adjacent Ku Morzu street as well as the beach.

None of the emergency scenarios at the LNG Terminal foresees a threat to the public at  Barlickiego street and the residential development on that street.

Emergency scenarios that may cause the hazard to expand beyond the LNG Terminal site:

  • LNG leak from the pipeline over the beach or at its location along Ku Morzu street.

Safety measures - welded pipelines, no bolted joints, placed in concrete channel, leak detection systems, video surveillance and monitoring by operators.

Hazard - possible ignition of LNG vapours, consequences - fire.

Alarming - evacuation alarm on the pier, voice announcements, in the area of the failure, about the existing danger and the evacuation order.

Instruction for people in the danger area - move away from the danger area, follow the instructions of the evacuation manager.

  • LNG or gas spill within the LNG Terminal site in the area adjacent to Ku Morzu street.

Safety measures - leak detection systems, hazardous zone shutdown system, plant shutdown and gas or LNG pressure reduction, video surveillance and monitoring by operators.

Hazard - possible ignition of LNG gas or vapours, consequences - fire, overpressure wave.

Alarming - evacuation alarm at the LNG Terminal, voice announcements, in the area of the failure, about the existing danger and the evacuation order.

Instruction for people in the danger area - move away from the danger area, follow the instructions of the evacuation manager.

7) Description of the procedure for warning and notifying the public of hazard and emergency

Notification to the public of an emergency threat or emergency occurrence via:

The LNG Terminal public address system, with loudspeakers located along the LNG Terminal technological pipe rack, ensures that emergency announcements can be heard on the adjacent beach and Ku Morzu street.

In addition, the following will be used:
- mass media (radio, TV, web portals)
- public address equipment installed on police, security or fire service vehicles

Notification of the population using: municipal, district crisis management centres and provincial crisis management centre

 

8) Description of actions to be taken by the population at risk and the procedure in case of emergency

In the event of an emergency scenario where the threat extends beyond the LNG Terminal site, people may need to be evacuated from the beach or Ku Morzu street in the vicinity of the LNG Terminal.

Taking into consideration the LNG Terminal in Świnoujście and the possible sudden and unforeseen immediate threat, a Level I evacuation will be implemented, which will involve immediate relocation of the population from the threatened areas/locations outside the danger zone. Level I evacuation is implemented immediately after the occurrence of a threat to life, health and property.

The person in charge of the rescue operation in the area covered by the operation may also announce a Level I evacuation.

9) Statement regarding the arrangements made on the site concerning cooperation with the services responsible for safety, when dealing with an accident and limiting its effects

The shift manager at the LNG Terminal, who in the first phase of the accident is the Leader of Emergency Operations, having received information about the accident and the possibility of the danger extending beyond the LNG Terminal site, activates the alarm systems and broadcasting of voice messages about the danger and evacuation, transmits the information about the accident to the Control Station of the City Headquarters of the State Fire Service in Świnoujście. If required, the shift manager notifies the Provincial Rescue Coordination Centre and the Provincial Inspectorate for Environmental Protection, and with regard of an accident on the sea part - the Harbour Master's Office.

10) Reference to the External Operational and Rescue Plan, including recommendations to follow instructions and orders of emergency services during an emergency

In order to limit and eliminate the consequences of the accident outside the LNG Terminal site, the Provincial Headquarters of the State Fire Service drafted an External Operational and Rescue Plan which includes recommendations to follow the instructions or orders of rescue services during an emergency.
